Description
【０００１】[0001]
本考案は、眼科用の治療およびまたは検査器械のための、好ましくは水平回転 軸の周りを旋回可能な網膜カメラ用案内弧に関する。 The present invention relates to a guide arc for an ophthalmic treatment and / or examination instrument for a retinal camera, which is preferably pivotable about a horizontal axis of rotation.
【０００２】[0002]
眼底カメラは、案内弧上を案内ローラにより移動する。案内弧とかみ合うギア 装置を有するハンドルにより器械の位置調節が行われる。自重による器械の移動 を防止するため、できるだけ大きい回転比の戻り止め付きギア装置を使用する必 要がある。 The fundus camera moves on the guide arc by the guide roller. The position of the instrument is adjusted by a handle having a gearing which meshes with the guide arc. In order to prevent movement of the instrument due to its own weight, it is necessary to use a detent gearing with a rotation ratio as high as possible.
【０００３】[0003]
従来の戻り止め付きギア装置はかなり高価で鈍重であり、大きな旋回経路にわ たる迅速な調節運動はできない。 Conventional detent gears are fairly expensive and blunt and do not allow for rapid adjustment movement over large swing paths.
【０００４】[0004]
本考案は、この欠点を回避することを課題とする。それは、主請求項の特徴記 載部分に基づく本考案の実施態様による適当な装置により実現される。他の有利 な形態は、従属請求項の対象である。 The present invention aims to avoid this drawback. It is realized by a suitable device according to an embodiment of the invention based on the characterizing part of the main claim. Other advantageous forms are the subject of the dependent claims.
【０００５】 ギア装置の操作を伴わない調節は、ハンドルギア装置が戻り止めを要しないた め器械で直接行うことも可能である。さらにそれによりギア装置がずっと簡単に なる。図２の阻止可能なばね脚部により、ハンドルギア装置さえ不要になる。長 いレバーは、容易な調節を保証する。調節可能な重量補償は、ばね平衡の各連結 点の調節および阻止可能な変更を、器械または支承部で行うことにより達成でき る。The non-operational adjustment of the gear device can also be carried out directly on the instrument, since the handle gear device does not require detents. Moreover, it makes the gearing much easier. The blockable spring legs of FIG. 2 eliminate even the need for handle gearing. The long lever ensures easy adjustment. Adjustable weight compensation can be achieved by adjusting and blocking changes at each spring balance connection point on the instrument or bearing.
【０００６】[0006]
【考案の実施の形態】 以下に図に示す実施例により本考案を詳細に説明する。DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the drawings.
【０００７】 回転軸Ｄを有する案内弧１は、部分的に示した検査器械３を点Ｂにおいて垂直 回転軸の周りを回転させるための回転軸受２に固定される。ここで回転軸受２は 、テーブル（図示せず）のボルト５の頂に被嵌されている。器械３は、器械に固 定した４個のローラ６により案内弧１上を案内され、ここでは回転軸受２に対し 器械３を重量平衡させるためのガス圧ばねとして形成したばね脚部７により支持 される。この場合点８において器械３、および点４において回転軸受２に固定さ れたばね脚部７の各固定点は補償すべき重量に依存するが、通常は平均重量に合 わせるので、器械３の運動に対してはできるだけ小さな残留応力を示す。しかし 点８と４について片方またはそれぞれに一つの可変に調節可能な連結点を，例え ば阻止可能な直線または弧状案内部（図示せず）に設置できる利点があるので、 追加的に各器械重量に調節できる。重量平衡を行うことにより、ローラ６による 案内弧に沿った器械３の粗動調節は、原理的に手動でも可能である。器械の微動 駆動は、そのあと図１ａに示す円板に固定したハンドル９により、この場合は小 歯車１１と軸１２により回転可能に器械３に支承される一体遊星ギア装置１０に より行われる。小歯車１１によるハンドル９の回転で遊星歯車１３は、ケーシン グに固定した内歯車１４で回転し、連結杆を介して歯車１５を回転させ、これが 案内弧１に挿入した部分歯車１６にかみ合うので、器械３が案内弧上を動く。ば ね付きボルト１７は、ハンドル９に対し内側からばねを押しつけ、装備の重いと きの器械の下降を防止するが、制動力より大きい力によって迅速な粗動調節を可 能にする。A guide arc 1 having an axis of rotation D is fixed to a rotary bearing 2 for rotating the partially shown inspection instrument 3 at a point B about a vertical axis of rotation. Here, the rotary bearing 2 is fitted on the top of a bolt 5 of a table (not shown). The instrument 3 is guided on a guide arc 1 by four rollers 6 fixed to the instrument, here supported by spring legs 7 formed as gas pressure springs for weight balancing the instrument 3 with respect to the rotary bearing 2. To be done. In this case, the fixing points of the instrument 3 at point 8 and of the spring leg 7 fixed to the rotary bearing 2 at point 4 depend on the weight to be compensated, but are usually matched to the average weight, so that It exhibits as little residual stress as possible with motion. However, because of the advantage that variable adjustable connection points, one on each side for points 8 and 4, or on each one, can be installed, for example on a straight line or arc guide (not shown) which can be blocked, the weight of each instrument is additionally determined. Can be adjusted to. By performing the weight balance, the coarse adjustment of the instrument 3 along the guide arc by the roller 6 can in principle also be done manually. The fine drive of the instrument is then carried out by means of a handle 9 fixed to the disc shown in FIG. 1a, in this case an integral planetary gear unit 10 which is rotatably mounted on the instrument 3 by means of a pinion gear 11 and a shaft 12. The rotation of the handle 9 by the small gear 11 causes the planetary gear 13 to rotate with the internal gear 14 fixed to the casing, and the gear 15 to rotate via the connecting rod, which meshes with the partial gear 16 inserted into the guide arc 1. , The instrument 3 moves on the guide arc. The barbed bolt 17 presses the spring against the handle 9 from the inside, preventing the instrument from lowering when the equipment is heavy, but allows a faster coarse adjustment with a force greater than the braking force.
【０００８】 図２には、ばね脚部に阻止可能なガスばね１８を設置し、その阻止はニップル １９の動作により解除できる。ガスばね１８の支承は、ここでは回転軸受２０で 行い、その中に阻止ニップル１９の変更のためピン２１を設置する。別のレバー ２２が回転軸受２３内で回転可能に支承され、この軸受は連結杆２４を介してガ スばね１８の懸架点８とともに一点で器械３に、そして他の一点３１でレバー２ ２に結合される。レバー２２は、把手２５を有し、その中にスラスト軸２６を設 置する。親指でスラスト軸２６を操作することにより、スラスト軸と結合したロ ッド２７によりロッドに連結され、点２９の周りを回転可能なレバー２８を傾斜 させ、ピン２１によりガスばねのニップル１９を作動させるので、阻止が解除さ れる。把手２５の運動は、連結棒２４を介して長いレバーと重量平衡により軽快 な器械３の傾斜の変更と、さらに垂直軸の周りの回転軸受２の回転も行わせる。 正確な調節点がわかれば、スラスト軸２６を親指で作動し、閉塞ガス圧ばね１８ により器械をその位置に固定できる。In FIG. 2, a blockable gas spring 18 is installed on the spring leg, and the block can be released by the operation of the nipple 19. The bearing of the gas spring 18 is here carried out by means of a rotary bearing 20, in which a pin 21 is provided for the modification of the blocking nipple 19. A further lever 22 is rotatably mounted in a rotary bearing 23, which is connected via a connecting rod 24 to the instrument 3 at one point with the suspension point 8 of the gas spring 18 and to the lever 22 at the other point 31. Be combined. The lever 22 has a handle 25 in which a thrust shaft 26 is installed. By operating the thrust shaft 26 with the thumb, the lever 27 connected to the thrust shaft is connected to the rod, and the lever 28 rotatable around the point 29 is tilted, and the pin 21 operates the nipple 19 of the gas spring. So that the blockage is released. The movement of the handle 25 causes a change of the inclination of the instrument 3 by the weight balance with the long lever via the connecting rod 24, and also the rotation of the rotary bearing 2 about the vertical axis. Once the exact adjustment point is known, the thrust shaft 26 can be thumb actuated and the obstruction gas pressure spring 18 locks the instrument in place.
